Patented Nov. 16, 1937 UNITED STATES TYPEWRITING MACHINE Burnham C. Stickney, Hillside, N. J., assignor to Underwood Elliott Fisher Company, New York, N. Y., a corporation of Delaware Application October 21, 1933, Serial No. 694,585

38 Claims.

This invention relates to manifolding worksheets that are separately collated with plies of carbon-webbing, the latter usually supplied upon spools mountable upon the typewriting machine.

An object is to simplify the construction and operation of the machine, and to reduce the cost, and especially to produce a device readily applicable to typewriting machines of standard construction, as, for example, the Underwood. The present invention is preferably an attachment, which may be mounted upon existing machines. The usual platen does not have to be swung up from normal printing position at the carbonhandling operation, as heretofore.

In the preferred manner of practicing the present improvements, a collating-board may be detachably mounted upon the usual standard paper-carriage, to extend backwardly from the delivery side of the platen. A front sheet-gage is dropped into position upon the platen. The work-sheets lie.face up and are separately a ed by their bottom edges. Leaves of carbon-web are laid upon the work-sheets; the carbon-webs being preferably rolled upon a spool which is journaled under the collating-table so that a loop hangs between the spool and the rear edge of the collating-table; the carbons being clipped against the rear edge of the table during the collating operation.

After the sheets are collated, an open sheetclip, which is mounted upon the platen, is closed to hold the forward edges of the sheets against the platen. Then the gage is swung up out of the way. The platen may then be rotated backwardly (preferably by means of a platen-sweep),

and by the aid of the clip the sheets are rolled downwardly and rearwardly under the platen.

During this part of the operation, the usual platen-rolls are cast off.

Then the clip releases the sheets, and is maintained in idle condition at a location between the platen and the front edge of the collating board, but below the level of the board. The clip remains at this place during the completion of the drawing of the sheets into the machine, and during the subsequent typing of the sheets.

Before the clip is released from the platen, as aforesaid, the feed-rolls are restored, to hold the sheets against the platen.

The platen-sweep, which may be connected by movement-multiplying gearing to the platen, may rotate the platen backwardly through two or three revolutions, and may be arrested by a settable stop in position to begin the typing of the first line on the work-sheet.

The typing of the sheet then proceeds line by line; the carbon-web hanging in a loop under the rear portion of the collating-board.

When the typing of the page is completed, the carbon-leaves are again clipped against the rear of the collating-board, whereupon the worksheets are all grasped by their lower edges and dislodged from the carbons and pulled out of the machine.

Then the platen-clip is advanced from its retirement to a temporary open position over the platen. Then the gage is swung down upon the platen just in rear of said clip, and the loading of the sheets with carbons proceeds as before.

Said gage consists of a series of teeth, and the clip has teeth which may pass between the gageteeth, so that the clip may secure the sheets against the platen while they remain set against the gage. The clip is thrown down upon the sheets, and then the gage is lifted, and the platen-sweep operated as before.

When the carbon-leaves become worn, fresh lengths of carbon-web may be pulled forwardly from the spool or spools and laid down upon the work-table, and then a knife may be swung forwardly from an idle position and placed upon the carbon-webs, to serve as a tear-off knife for the waste carbon-leaves. Then the knife may be swung to an idle position back of the collatingboard.

The invention is inexpensively made and readily attached to the carriage of an Underwood machine, without necessitating substantial alteration of construction or operation of the machine or of the carriage. The changes are immaterial, and the new parts operated by the platen may be readily attached after removing the platen from the machine whereupon the platen and its new attachments may be replaced. The invention employs only a few parts, which are all inexpensive.

The accompanying drawings or diagrams are principally side elevations, and successive stages are illustrated in the relation of the sheets and the carbons, first interleaving the sheets, then carrying them forwardly and downwardly around the platen preparatory to typing the same line by line, and finally withdrawing the sheets from the carbon-webs, the latter being retained in the machine.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 shows the front sheet-gage about midway between its normal and working positions,

iii

where it may stand while the typed work-sheets are dislodged and withdrawn.

From the Figure 1 position, the gage is swung down to the platen, as shown in Figure 2, this figure showing the first work-sheet as overlying a carbon which has been placed upon the collating-table. The sheet-clip is shown cast ofi from the platen.

Figure 3 is a plan of the revcluble platen and the sheet-clip, the latter being hinged upon a. bail which is hinged upon the platen-hubs.

Figure 4 shows the completion of the collation of the sheets and carbons against the front gage.

Figure 5 shows the clip as having been thrown against the platen to clamp the sheets thereto while they still remain set against the front gage. From this position, the front gage is thrown up to the dotted-line clear position as seen at Figure 4, where it stands idle during the introduction, typing and withdrawal of the work-sheets.

Figure 6 is a perspective showing the sheets clipped as at Figure 5, and showing the gage swung up from the platen.

Figure '1 shows a plan of the carbon-supply roll.

Figure 8 corresponds mainly with Figure 6, and shows the carbon-plies released preparatoryto rotation of the platen and the collated sheets (the carbons having been automatically clipped at their rear portions for the sheet-collating operation).

Figure 9 shows the clipped sheets as having been carried around the front and bottom of the platen, from which the feed-rolls stand released.

Figure 10 shows the clip as having passed by the feed-rolls, and the latter as having been restored against the platen. This is preparatory to the automatic release of the sheet-clip.

Figure 11 shows the clip released from the platen and occupying a retired position near the upper rear part of the platen, beneath the incoming work-sheets, and forwardly of the collating-table.

Figure 12 shows a still later stage, in which the work-sheets have been retracted far enough to type the first line thereon.

Figure 13 shows the typing of the work-sheets as having been completed. The sheets have advanced line by line past the bottom feed-rolls, and are ready to be grasped as seen at Figure 1, and withdrawn from the carbon-plies. The lat- -ter are clipped against the rear edge of the collating-table. This clip has stood idly in the Figure 13 position, since its automatic release shown at Figure 11, and throughout the typing of the page.

Figure 14 is a plan showing the rear end of the collating-table which has adjustable side-gages, or is adjustable in width. This figure also shows the carbon-clip in open position.

Figure 15 is a side elevation seen from the left side of the machine, showing a portion of the typewriter-carriage with the sweep-mechanism for rotating the platen backwardly to feed the collated sheets into the machine. This figure also shows the means for automatically throwing out the line-space spring-detent during such rearward rotation of the platen.

Work-sheets are collated upon a table 2|, extending rearwardly from the top or delivery side of the revcluble platen 22 of an Underwood typewriter. The table 2| may be supported upon a cross-bar 23 of a bracket having side plates 24 secured by screws 25 to the typewriter-carriage 26, the latter running along a fixed track 21. The collating-table 2| inclines downwardly and forwardly towards the delivery side of the platen, but may be spaced considerably therefrom. The table has side guides 28 for the worksheets, and is preferably made in opposite widthwise sections, as seen at 2|, 21', Figure 6, adjustable towards and. away from each other, and secured by screws 29. The table may have rear sight-openings 30 to expose a carbon-supply spool 3| beneath the table, said spool being mounted upon an axle 32, journaled in side arms 33 formed upon the bracket. 24. The spool may carry one or a plurality of plies of carbon 34 which may drop from the front side of the spool and hang in a loop running to the rear end of the collating-board 2 I. Thus the weight of spool and its carbon-web is brought" nearer the carriage-guiding track 21, thus conducing to smooth and rapid operation of the heavy carriage and platen.

Before collating the sheets, a front sheet-gage 35 may be swung downwardly and forwardly from its normal upstanding idle position, at Figure 8, to rest upon the top of the platen 22. This gage 35 may be in the form of a bar which is seen at Figure 6 extending the length of the platen and supported upon a pair of side arms 36, which are hinged upon a rock-shaft 31 that is journaled upon the ends 38 of the usual frame in which the platen-axle 39 is journaled. Said gage-shaft 31 may be journaled in a pair of plates 40 that are bent down from a pair of top plates 41 secured by screws 42 upon the platen-frame ends 38. The gage is pressed against the platen by a double-acting spring 43; the latter serving also to detain the gage in its upstanding idle position, Figure 8, where it is held against its stop-pin 40. The gage having been swung down upon the platen, the work-sheets are collated one by one upon the table 21. After depositing the first work-sheet, a carbon-leaf 34 is swung down thereon; and after depositing the second worksheet, another carbon-leaf is swung down, and

so on.

The carbon-leaves at this time are held by a clip 44 against the rear beaded end 45 of the collating-table 2|, Figure 4. This clip is mounted upon a rock-shaft 46 at the rear of the table, Figure 8, and is provided with a closing spring 41. However, the clip is normally held open by a pin 48, which bears against the end of an operating rod 49, the latter being pivoted at its rear end at 50 to an arm 51 extending down from the rock-shaft 46. The forward end of the rod 49 is supported and guided by a pin 24 fixed to the bracket 24 and extending through a slot 52 in the rod 49. The aforesaid spring 43 is strong enough to hold the clip open when the gage 35 is in idle position, Figure 8.

Said pin 48 is provided upon the left-hand arm 36, and the rod 49 is provided with a fingerpiece 53, whereby the clip 44 may be thrown off at will.

The forward ends of the gaged sheets overlie the platen in position for holding them to the platen by means of a clip 54, which, during the collating operation, occupies an idle upstanding position in front of the gage, as at Figure 2. It may be observed that, during the operation of typing these sheets, said clip occupies an idle position seen at Figures 11, 12 and 13, below the path of the work-sheets, between the top of the platen and the front edge of the collating-table 2 I; but, when swinging downwardly and forwardly the front gage-bar 35 to working position, said open clip 54 is brought forwardly above the platen to a temporary idle position, seen at Figure 4, preparatory to being swung down upon the assembled work-sheets. The clip swings from open to closed position upon a pair of side arms 56, formed upon the clip and pivoted at 55 to a pair of plates 51. Said clip and its side arms form a ball which in this manner is hinged at 55 to a mount, which is also in the form of a bail, its side arms orplates 51 having a connecting bar 58 which extends from end to end of the platen; the bail-mount 51, 58 is pivoted upon the hubs 59 of the usual platen-heads between the platenframe ends 38, permitting rotation of the platen independently of the clip. The clip-bail.and the mount swing as a unit around the platen-hubs 59 from idle position at Figures 11 to 13, to temporary forward position at Figure 4.

The clip swings down upon the sheets while their front edges remain in contact with gage 35. To reach its working position, the clip must pass the gage, and for this purpose the gage is made in the form of a series of separated teeth 60, as at Figure 6, and the clip is likewise made of a series of separated teeth 6 I, said teeth 6| swinging through the spaces between the gage-teeth 60, and dropping upon the work, as at Figure 5, Preparatory to backward rotation of the platen for drawing the work downwardly around the front of the platen and rearwardly under the same and upwardly along the paper-shelf 62 which usually forms part of said platen-frame.

The usual front and rear bottom feed-rolls 63, 64 are cast off by the gage-bail 35 when the gageis swung down to the working position, Figure 4. Such release of the rolls is effected by link 65, whose upper end is pivoted at 66 to a short arm 61 formed upon one of the bail-arms 36. The lower end of this link connects to a pivot-pin 68 provided upon arms 69 formed upon a rock-shaft 18 having cutaways forming cams 1|. These cams usually operate between arms 12 of bellcranks which carry the rolls 63, 64, and separate the arms and lock the rolls in cast-off positions, as at Figure 4, where they stand during the early portion of the introductory rotation of the platen, as long as the sheet-clip 54 remains in use. The lower end of said link is slotted longitudinally as at 13 to permit manipulation at any time of the usual roll-releasing link 14 and its key-lever 15, seen at Figure 9.

The described rotation of the clip-unit may be effected by means of a ratchet-wheel 16 that is fixed to the platen and is engageable by a drivepawl 11,which, during the typing operation, stands released from the ratchet-wheel, as seen at Figure 4. This drive-pawl is held out by means of a pin 18 that projects from a side arm 56 of the clip-bail, as seen at Figure 4; but, when the operator throws the clip rearwardly and down to working position, the pawl 11 is permitted to be drawn into engagement with the ratchet 16 by means of a spring 19. This engagement is maintained so long as the clip remains closed.

The clip-bail is held in both open and closed positions by means of a double-acting spring 80, which is pivoted at 8| to the mount-arm 51, the other end of the spring being pivotally connected to the side arm 56 of the clip.

Thus the pawl is automatically moved into engagement with the ratchet-wheel, so thatbackward rotation of the platen will drive the clip-unit bodily around with the platen; neither the pawl nor the clip being released until after the worksheets are caught by the feed-rolls 63, 64, as now to be described.

As the closed clip 54 passes by the bottom rolls 63, 64, Figure 9, a cam 8| (which is formed upon one of the end plates 51 of the clip-mount, and which therefore is being driven by the pawl 11) engages a pin Bi that projects from the key-link 14 of the feed-roll mechanism, and forces down said link, thereby permitting the usual springs 8 l to restore the rolls to the platen, as at Figure 10. The rolls thereafter co-operate in the usual way with the platen, whereby the sheets continue to be drawn into the machine; and subsequently they are line-spaced forwardly by the aid of the rolls and the platen in the usual way.

The platen-wheel 16 no longer needs to drive the clip-mount around, and the mount may therefore be released from said wheel, the clip being first automatically opened.

It has been seen that the work-sheets have been drawn in past the rear feed-roll 64, and since the clip has nothing further to do, as at Figure 9, there is utilized a fixed cam-edge 82 that is formed upon a plate 83, Figures 9 and 10, secured to the right-hand platen-frame end 38, Figure 6. This plate 83 is bent down from the right-hand top plate 4|. Cam 82 is in the path of a pin 81 that projects from one of the side arms 56 of the clip-bail, Figures 6 and 9. When the pin 81 is intercepted by said cam during the further rotation of the platen, the clip-bail is gradually swung to its open position, where it is held by the double-acting spring 80, Figure 11.

It being no longer necessary for the pawl 11 to drive the clip-unit, it is automatically disengaged from the ratchet-wheel 16. For effecting this disengagement, pin 18 is brought into use. During the swinging of the clip-unit outwardly from the platen, said pin engages the underside of the pawl, and lifts it out of the notch in the ratchet-wheel.

At this time the clip occupies a normal idle position between the intake and delivery sides of the platen, or just beneath the work-sheets, the clip nearly bridging the space between the platen and the forward end of the collating-table 2|, as at Figures 11-13.

The platen continues to rotate backwardly to retract the collated sheets until they reach position for starting to type. v

During the typing of the page line by line, the ratchet-wheel 16 rotates idly with the platen; while the sheet-clipping unit 54, 58 remains stationary in idle position, as seen at Figure 13, and the gage 35 remains in its elevated idle position.

At the time of the beginning of the typing, the position of parts is seen at Figure 12, the rear ends of the collated sheets being deflected downwardly by a deflector 88 away from the carbonspool 31.

The idle clip-unit, Figures 11, 12, is held stationary by means of a detent in the form of a spring-pressed hook 89, which is pivoted at 96 upon one of the gage-arms 36,, this hook 89 having a spring ill] and being provided with a notch which engages pin 9| of the clip-mount 51.

The hook 89 is pivoted to the-gage-bail 35, thereby enabling the gage-bail to rotate the clipunit from permanent idle position, Figure 13, to its forward temporary idle position, Figure 4, in front of the gage 35, where it is still out of the way while the sheets are being collated, but is positioned to swing backwardly and down, so as to clip the collated sheets to the platen, Figure 6.

When the clip-mount 51 reaches its forward position at Figure 4, it is stopped by an elbow 92, which extends down from a side arm 36 of the gage-bail 35, see Figure 4. Said elbow 92 is in the path of pin 9I, and is encountered thereby, and further forward rotation of the clip-unit is prevented. The clip-unit is therefore locked by 89 and 92 in the Figure 4 position. Owing to the lengthening of elbow 92, the top gage 35 may be swung up without relinquishing control of the clip-mount. This control is maintained until the hook 89 cams itself free from pin 9I, by means of cam 92, whereby the clip-unit is freed from the hook and the elbow concomitantly, and is ready to be driven around by pawl 11.

During the typing of the page, the collated sheets feed forwardly and up around the platen and back over the table 2|; the carbons dropping to form a loop below the carbon-spool.

At the conclusion of the typing of the page, the operator may pull forward the gage-bail with its pin 48, thereby permitting the link-spring 41, Figure 4, to close the clip 44 to clip the carbonwebs to the rear end of the table 2|, Figure 1.

At this time the operator may grasp the forward ends of the work-sheets 20, to dislodge them from the carbons and pull them out of the machine.

He may then press down the gage from the intermediate Figure 1 position to the position at Figure 2, to swing the clip-unit forwardly by means of the hook 89 to the temporary forward position at Figure 2. The gage is brought down to the top of the platen, preparatory to collating a fresh set of work-sheets in the manner already explained.

There may be provided a platen-sweep mechanism, Figures 4 and 15, for rotating the platen backwardly to draw the collated sheets around the platen as described.

The platen-sweep may have capacity for three platen revolutions to bring long sheets from the position at Figures 4 and 6 to that at Figure 12 at a single stroke of the platen-sweep handle 93. This platen-sweep mechanism may be adapted from Waldheim Patent No. 1,578,941, of March 30, 1926; the same having a normally disengaged pawl 94, which, by means of handle 93, the operator presses down into a notch in the ratchetwheel 95, having a pitch corresponding to the line-spacing of the platen. By means of this ratchet-wheel, a large gear 96 is caused to rotate a driving pinion 91 fixed upon the platen-axle. The extent of platen rotation depends upon the setting of a stop 98, for which there are provided location-holes 99.

The handle, ratchet-wheel and gear may be mounted upon a vertical bracket-plate I00, which may be anchored upon the platen-axle 39, and may also have a link-anchorage IOI secured to the platen-frame end 38.

The platen has the usual line-spacing mechanism, including ratchet-wheel I02 with its springdetent roll I03. To avoid the noise of the detent, the latter may be automatically thrown out by a cam I04, which is adapted from Kurowski Patent No. 1,141,558, of June 1, 1915. Said cam I04 is formed upon the end of a lever I05, having at its opposite end a roll I06 which follows a cam I01 which may be connected to the handle 93.

The carbon-roll 3| may be held steady by a spring-washer I08, Figure 6, pressed lightly against a collar I09 fixed upon the spool or shaft 32, and permitting one or more plies of carbon to be drawn off the spool to form fresh leaves.

When a length of fresh carbon has been drawn from the spool, a knife II I may be swung into the carbon-severing position seen in dotted lines at Figure 4. This knife III is carried by a pair of bail-arms II2, hinged at II3 to opposite arms II 4 extending up from the bracket-plates 33. The arm may normally rest upon' rear-bosses I IS, in which are journaled the ends of clip-shaft 40. When in this position, shown in full lines at Figure 4, the knife-bail is back out of the way, leaving an unobstructed space for the manipulation of the work-sheets and carbon-leaves; while the knife may be readily swung forward about the hinge II3 to the dotted-line severing position at the front of table 2|. The side gages of the table lie between the knife-bail arms H2, and said gages, near their forward ends, have cutaways IIB into which the knife-blade III may drop upon the carbon-leaves, to hold them down upon the table as the worn-out leaves are torn off.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
